In my installation of Potterton there was nothing connected to '1'; I wired everything else and heating works well, but hot water setting do not appear to be influencing the boiler (although the schedule did work with the Potterton device); any thoughts?

Can I just double check, before I do something daft - the Nest has warnings to not connect it to 240v systems, and yet isn't this one? Edited: sorry - silly me - it is the thermostat that needs to be 12v
